  • the safety cabin is designed to perform analyses and measurements by means of various types of optical techniques, particularly those based on recording and acquiring images by means of an analysis chamber and lighting systems which can be used to detect and identify contaminants, toxic, biological or chemical agents without endangering the operators performing the study or the environment.
  • safety cabins intended to be used as equipment in biological and chemical laboratories are known in the state of the art. They are closed and sometimes ventilated spaces which enable the operator to act safely with harmful substances. They are especially used for handling dangerous or toxic products, such as, for example, chemical substances or for analysing viruses, bacteria, etc.
  • the present invention relates to a portable safety cabin for optical analysis of substance samples, wherein the cabin comprises a partially transparent analysis chamber intended to house the substance, limited by a base intended to rest on a support surface, four vertical panels which extend from the base and a ceiling panel connected to the vertical panels.
  • the safety cabin comprises a work tray resting on the base and housed in the analysis chamber intended to support the substance, a gas inlet valve connected to one of the vertical panels intended to be connected to an external gas source and introduce gas into the analysis chamber and a gas outlet valve connected to one of the vertical panels through which a contaminated gas is evacuated to the outside of the analysis chamber.
  • the safety cabin is equipped with a transfer chamber through which the substance is introduced into the analysis chamber and it is equipped with an opening arranged in one of the vertical panels communicating the inside and outside of the analysis chamber.
  • the cabin comprises at least two access cavities which cross through one of the vertical panels and a glove housed in the analysis chamber which extends from the access cavity.

Thanks to the movable supports, the optical analysis and lighting equipment can be easily installed inside the cabin and the position thereof can be adjusted according to the requirements of the different optical techniques.
  • the location of the cabin can vary greatly, from a fixed laboratory to a mobile platform, the transfer and installation thereof being quick and simple.
  • Potential applications in the industry focus on the optical analysis of hazardous substances, using a sample of the substance to do so, in environments such as scenarios of leakage or spills of potentially dangerous or contaminating products, the inspection of facilities such as chemical plants, refineries and the evaluation of contamination of the natural environment.

  • the cabin comprises inner switches housed in the chamber (1) and outer switches on the outside of the chamber (1), wherein the switches are connected to the strip and are intended to be connected to the optical equipment (19) and lighting equipment (49) through an airtight inlet and outlet system of the power and data cables (50).
  • the contaminated gas crosses through a HEPA filter on the outside of the cabin and, once filtered, is expelled to the outside environment.
  • transport handles (34) are seen which extend between two of the vertical panels (4,5,6,7) opposite from each other, specifically from the side panels (4,5) and an adjustable platform (35) connected to the base (2) and intended to rest on the support surface (3).
  • the anchors (36) connected to the ceiling (8) are shown.
  • FIG 4 shows a schematic profile view of the safety cabin, according to the present invention, wherein it can be seen that the cabin is equipped with outer light-regulating panels (26) which in the figure shown are photochromic panels and the vertical panels (4,5,6,7) comprise joining elements (27) in the vicinity of the vertices thereof.
  • the joining elements are projections which are arranged in the vicinity of the base (2), as a square, generating a slot wherein the photochromic panels are introduced.
  • Figure 5 shows a schematic front view of the inside of the analysis chamber (1), wherein it can be seen that the cabin comprises a rotating support (29) connected to the work tray (21), preferably circular, and to the base (2), which enables the rotation of the work tray (21) and a collection tray (30) resting on the base (2) intended to collect waste of the substance, wherein the collection tray (30) has the edges curved towards the central area thereof in order to prevent the waste and leakage from spilling.
  • the cabin comprises a rotating support (29) connected to the work tray (21), preferably circular, and to the base (2), which enables the rotation of the work tray (21) and a collection tray (30) resting on the base (2) intended to collect waste of the substance, wherein the collection tray (30) has the edges curved towards the central area thereof in order to prevent the waste and leakage from spilling.
  • the cabin comprises a decontamination liquid tank (53), equipped with a motor not shown in the figure, connected to a tube (51) which extends through the inside of the analysis chamber (1) through which a decontamination liquid is made to pass, provided with suitable openings so that the decontamination liquid comes out in the form of a spray and is introduced into the analysis chamber (1), decontaminating it.
  • It additionally comprises at least one button (52) for turning the system on or off connected to the motor, on the outside of the analysis chamber (1) near the decontamination liquid tank (53), wherein it preferably comprises another button, not shown in the figure, on the inside of the cabin in order to enable the actuation thereof in case of emergency, both from inside the analysis chamber (1) and outside it.
  • a set of sensors (54) for the analysis chamber is seen equipped with at least one accelerometer intended to be connected to a microprocessor which sends the data from the accelerometer to a mobile device.
  • the set of sensors comprises pressure sensors arranged on the inside and outside of the analysis chamber which measure the pressure in order to ensure that the pressure inside the chamber is negative. Additionally, it comprises temperature sensors, moisture sensors, etc.
  • the ultraviolet light decontamination system (55) and the video recording system (56) joined to the frame (16) are seen.
